A carrier bracket for use with a power cylinder of the type having an elongated cylinder member and a reciprocally movable piston therein for transferring reciprocal movement of the piston to a desired work piece. The carrier bracket includes a central bracket portion, a pair of guide arms extending outwardly from the central bracket portion, an elongated bearing rod secured in a fixed position relative to each of the inner surfaces of the guide arms, a mechanism to permit limited flexing movement of the arms relative to the central bracket so as to facilitate the limited selective movement of the arms toward and away from one another and a device for causing the limited selected movement of the arms toward and away from one another.
